HVAC stands for “heating, ventilation and air conditioning,” three functions often combined into one system in today’s modern homes and buildings. Warmed or cooled or dehumidified air flows through a series of tubes – called ducts – to be distributed to all the rooms of your house. A central HVAC system is the most quiet and convenient way to cool an entire home.

Another modern development in the HVAC industry is the "whole house" approach to heating and cooling. Coupled with an energy efficient furnace, heat pump or air-conditioner, the whole house approach can have a great impact on your energy bills. By combining proper equipment maintenance and upgrades with appropriate insulation, weatherization and thermostat settings – properly regulated with a programmable thermostat – you may be able to cut your energy bills in half.

Like many other appliances, HVAC systems have improved in energy efficiency in the last decade. As a result, you can save money and increase your comfort by properly maintaining and upgrading your HVAC equipment.
